China's Rare Earth Leverage Looms over Xi-Trump Summit

As President Xi Jinping prepares to meet with President Donald Trump this week, the trajectory of the summit is likely to be heavily influenced by China’s continued dominance in the rare-earth sector. Although the two nations have maintained a one-year trade truce that expires in November, the underlying structural dependency of the United States on Chinese mineral processing remains a significant point of tension. This meeting arrives at a critical juncture where diplomatic maneuvering intersects with deep industrial vulnerabilities that have persisted since the initial tariff escalations of early 2025.

The rare-earth issue has become a central pillar of US-China economic friction. After Washington introduced broad tariffs, Beijing retaliated with export restrictions on critical minerals, forcing both sides into a series of negotiations that culminated in the current temporary agreement. According to Foreign Policy, the administration has since launched an aggressive campaign to reduce these vulnerabilities, yet recent data suggests that the gap between policy goals and industrial reality remains wide. Chinese shipments of rare-earth magnets to the US dropped again in August, a trend that underscores the fragility of American supply lines despite diplomatic efforts to stabilize trade.

Persistent Dependence on Chinese Inputs

U.S. Trade Representative Jamieson Greer has assessed China’s performance on rare-earth exports as merely a “passing grade,” highlighting the limited progress made in diversifying supply sources. Experts note that the integration of Chinese goods into global production stages is so extensive that unwinding these dependencies is a complex, long-term process. Even with new investments and deals announced by the Trump administration since April, the structural reliance on Chinese mining, separation, and magnet production technologies continues to define the economic landscape.

Chris Kennedy, a former National Security Council director for international economics, emphasized that this dependence is unlikely to disappear in the near term. According to Bloomberg Economics, China is estimated to maintain its dominant position in rare-earth supply chains until at least 2030. Kennedy pointed out that even production facilities outside of China, such as those in Japan, often rely on Chinese inputs and technology, creating a web of interdependencies that is difficult to sever quickly. This persistence means that the rare-earth card will remain a potent tool in Beijing’s diplomatic arsenal for the foreseeable future.

Diplomatic Expectations and Trade Truce

In the lead-up to the summit, analysts suggest that both Washington and Beijing recognize the mutual benefit of maintaining the current truce. Cory Combs, head of critical mineral research at Trivium China, stated that neither side wishes to destabilize the existing framework. Greer has indicated that Washington may support a short-term extension of three to six months, a move that would provide additional time for the US to develop alternative supply chains without immediately triggering a full-scale trade conflict. This cautious approach reflects a shared desire to manage tensions rather than escalate them during this high-stakes engagement.

Jennifer Welch, a geoeconomics analyst at Bloomberg Economics, noted that while the US is dissatisfied with the current flow of rare earths, policymakers are wary of actions that could completely shut off access. This delicate balance is likely to shape the outcomes of the Xi-Trump meeting, which may also touch on broader issues such as artificial intelligence and Taiwan. The consensus among experts is that while a truce extension is probable, it will not resolve the fundamental strategic imbalance. Instead, it will serve as a bridge to a longer period of negotiation and gradual decoupling, with the rare-earth sector remaining a focal point of US-China relations well into the next decade.
